3. Earth formed about 4.6 billion years ago during the birth of our solar system. ... During the next major phase of earth's formation cooling and differentiation of the Earth's layers occurred. Dense materials sank to the center, forming an iron-nickel rich core. Lighter buoyant silicate-rich magma rose to the surface.
4. Instead of using CAT-scans and X-rays to see the center of the Earth, researchers use waves emitted by earthquakes to get a sense of the planet's innards. ... These tests are what allowed scientists to see that the core of the Earth is broken into three layers all with slightly different structures
5. Scientists believe Earth's magnetic field results from movements of molten iron and nickel within its liquid outer core. ... Earth's magnetic field is essential for life on Earth

A region of metamorphic rock lies far beneath the earths surface, in time which two ways can the rock make its way upward to earths surface where people are able to see it.
Answers
Explanation:
Rocks produced by rising pressure and temperature are metamorphic rocks. These are secondary rocks and are developed directly from igneous, sedimentary, and other metamorphic rocks. Schist, gneiss, marble, quartzite, among the few examples.
Both on and below the surface of the planet exist these rocks. These rock types may be exposed to an outcrop if the rock is molten owing to the extremely high temperature, resulting in magma melting and crystallizing further by reducing the temperature and forming an extrusive kind of igneous rock.
These rocks can also be placed on the surface where they are compelled to grow into a convergent or a divergent sort of plate-type tectonic border comprising such metamorphic rocks.
Answer:
B. It can uplift slowly due to the pressure of Earth’s plates.
E.It can melt into magma and recrystallize as extrusive igneous rock.

Which of the following air masses is most likely to produce a blizzard?
Answers
Answer:
cP
Explanation:
hope this helps
The warm and humid air masses are separated by the cold air mass, and as the warm moist air rises, it condenses to make snow. The air mass collisions also produce the atmospheric tension necessary for strong wind speeds. Thus, option B is correct.
What is the air masses blizzards related to cP?Blizzards typically develop when two masses of air—one warmer and the other much colder—interact.
For cP air masses in the contiguous United States, Canada is the most frequent source country. Continental Arctic (cA): The coldest air masses of winter. The coldest and driest air masses are those from the letter c.
Cold, dry, and stable air masses are found in the continental polar (cP) or continental arctic (cA) regions. They travel south, then east via the Plains and the Rockies.
Therefore, cP air masses are most likely to produce a blizzard.

Molten, or hot liquefied, rock located deep below the Earth's surface is called magma. Magma is formed when temperatures within Earth's crust or mantle are very hot and when pressure in places within those layers decreases. When a volcano erupts or a deep crack occurs in the Earth, the magma rises and overflows.
